I found an interesting article on child's blood pressure. Blood pressure will change as the child grows, height and weight are a determining factor of blood pressure for children. The link is posted below.
The blood pressure for children 5-13 is 90 that is the best blood pressure if its higher than that consult a physician
120/80
110/80
The ideal blood pressure for 40 year old males varies according to activity level. Doctors recommend that blood pressure be lower than 120/80 at almost any age.

Yes, children can have low or high blood pressure.
high blood pressure may be to do with diabetes.
The ideal numbers for a healthy blood pressure reading are less than 120. Anything above 120 is considered high blood pressure and one should immediately see a doctor.
The blood pressure of 103/61 is not all right for a 45 year old male. The ideal blood pressure should be between 115/75 and 120/80.
A healthy blood pressure range would be 120/80. Often if your blood pressure is higher than this you will be told you have high blood pressure and anything lower would be low blood pressure. If your blood pressure is over 140 then you should take steps to reduce this.
There are two number involved in blood pressure--the ideal top number (systolic pressure) should be less than 120 and the ideal lower number should be (diastolic pressure) should be less than 80. So the ideal pressure should be 120/70 or so. You have "pre-hypertension" or borderline high blood pressure if the top number is consistently 120 to 139 or the bottom number reads 80 to 89. You have hypertension or high blood pressure if the top number is consistently 160 or over or the bottom number reads 100 or over. You have low blood pressure (not a good thing either!) if the top number reading is lower than 90 or the pressure is 25 mmHg lower than usual. I suggest you check out the links recommended by the National Library of Medicine website, MedlinePlus (http://medlineplus.gov). This site has links that explains high blood pressure http://www.nlm.nih.gov/medlineplus/highbloodpressure.html. This site has links that explain low blood pressure http://www.nlm.nih.gov/medlineplus/lowbloodpressure.html These ideal numbers remain "ideal" whatever your age or whether you are male or female. So, the normal "good" or "ideal" blood pressure should be around 120/70 or 120/80.
High blood pressure is measured as two numbers, systolic pressure over diastolic pressure. Any reading of 140/90 or higher is considered high blood pressure.
